But the colon operator can work between two variables truncating the
longer to length of the shorter during comparison...

If a =: b;


Both of these keep the observation:
data test;
     a='a';
     aa='aa';
     if a=:aa;
run;

data test;
     a='a ';
     aa='aa';
     if trim(a)=:aa;
run;

By the way, there are other possibilities to get the same. Look at the
following:

data _null_;
  set sashelp.class;
  where name like "A%";
run;

However the LIKE operator has many other possibilties. "%" stands for
all
chars, "_" for a single one

e.g. "_a%c%" means: the second char is a "a" and the rest contains a "c"
anywhere...
